OK - first contribution. A beautiful tune and one that I think sounds best with 
finger picking - play about with the patterns until you get it sounding good.

Chords for intro:

Am - Em - C - G; G - D - C - G (same as last two lines on verse)

Verse:

Am          Em           C          G
Away to the westward I'm longing to be,

                      Em     G             D
Where the beauties of heaven unfold by the sea,

          Am           Em              C            G
Where the sweet purple heather blooins fragrent and free,

               D                   C    G
On a hill-top, high above the dark island.
